1) The document discusses current challenges in accounting for city emissions and presents projections showing that without policy changes to reduce emissions, average global temperatures could rise by 3-4 degrees Celsius by 2100. 2) It shows annual CO2 emission projections for different scenarios, ranging from a 1.6 degree Celsius rise with stringent climate policies to a 4.3 degree rise with no new policies. 3) The presentation notes that the "climate game may be beginning to change" and discusses existing, emerging and potential emissions trading schemes.

scenario
4.3°C (RCP8.5) No policy change to reduce emissions
2.8°C (RCP6.0) CO2 emissions peak in 2075, methane
emissions are stable from now.
2.4°C (RCP4.5) Stringent climate policies,
lower energy intensity, strong
reforestation programmes . Emissions
peak in 2040
1.6°C (RCP2.6) Low energy intensity, Methane
emissions reduced by 40%, a world
population of 9 billion by 2100 – much
slower population growth than in
most models
